目的探讨不同应激水平对职业人群的皮质醇分泌的影响。方法选择某铁路职业421人,用职业紧张量表(OSI-R)调查其职业应激水平,测定皮质醇(COR)含量并对结果进行分析。结果职业应激中乘警评分最高(273.1±37.0),其皮质醇浓度也高于乘务员和一般办公人员。职业应激总分中,高评分组的皮质醇浓度高于中、低评分组,应激反应高评分组的皮质醇浓度高于中评分组,应激源对皮质醇浓度的影响无统计学意义。结论皮质醇能在一定程度上反映职业应激的负荷水平,可以考虑作为评价职业应激的生物指标之一。
Objective To investigate the effects of different stress levels on cortisol secretion in professional population. Methods A total of 421 railway occupations were selected. OSI-R was used to investigate occupational stress levels. COR contents were measured and the results were analyzed. Results The highest score of occupational stress was maternity police (273.1 ± 37.0), and its cortisol concentration was also higher than flight attendants and general staff. Cortisol concentrations were higher in middle and high scores of occupational stress than in middle and low scores, and cortisol concentrations in high stress scores were higher than those in middle scores. There was no significant difference between stress stress and cortisol significance. Conclusion Cortisol can reflect the stress level of occupational stress to a certain extent and can be considered as one of the biological indicators to evaluate occupational stress.
